(the NDK maintainer points out that we do however make canary builds
available[https://android.googlesource.com/platform/ndk/+/master/docs/ContinuousBuilds.md]
--- note that the downloads default to darwin, so you'll want to
change that combo box too if you're following the instructions but use
linux.)
